Abstract: Protection of elements (1) of composite material protected at its points of complex geometry, such as various edges and corners, against electric discharges to which they are potentially exposed, said elements (1) being obtained by applying a cycle of temperature and pressure to a composite material arranged in a mold (2) designed in such a way that, once the geometry of the element (1) is known, the mold (2) includes free spaces (6) intended for the accumulation of resin from the process of manufacture of said element (1), and said resin will form the dielectric protection of the various edges or corners of the element (1) as it builds up, forming layers (3) that are disposed around the free edges of the element (1), thus endowing these surfaces of various edges or corners with dielectric protection of electrical insulation that prevents possible discharges and expulsion of hot particles in the case of electric discharge on said element (1).

Abstract: A metalization structure of aircraft panels and process for obtaining such structure including a panel made in composite material, the panel including a metal mesh or foil in its outer part, said panel further including a bore which in turn comprises a shank and an upper countersinking, such that the mentioned panel is fixed to another structural aircraft element by means of metal fixing elements. The structure includes a metallization layer arranged on the upper countersinking, extending in the adjacent area of the metal mesh or foil, such that it is ensured that electrical continuity exists between the upper countersinking and the metal mesh or foil during the time that the lightning bolt strikes the structure of the panel, further ensuring that most of the current discharged by the lightning bolt is conducted over the surface of the structure of the panel.
